Hash : b610b2b9
Message : Rename XKBcommonint.h to xkb-priv.h and use it Make the files in the src/* directory use their own header or a consilidated private header. This makes the file dependencies clearer. Also drop the pointless "xkb" file name prefix, add split a few declarations to their own files (atom.h and text.h). Signed-off-by: Ran Benita <ran234@gmail.com>
